Web 3.0 refers to a paradigm shift in how the internet operates, moving from a centralized model to a decentralized architecture. It is built on blockchain technology which allows for secure, peer-to-peer interactions. Users in Web 3.0 have greater control over their digital identity and data, fostering an environment of privacy, ownership, and transparency. Decentralized applications (dApps) and smart contracts enable new functionalities that challenge traditional business models and provide innovative services across various industries.
